A table or chart of nuclides is a two-dimensional graph of isotopes of the elements, in which one axis represents the number of neutrons (symbol N) and the other represents the number of protons (atomic number, symbol Z) in the atomic nucleus. Each point plotted on the graph thus represents a nuclide of a known or hypothetical chemical element.
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. 801–873 AD), who formally developed the method (the ciphers breakable by this technique go ...
List of colors: A–F. Colors are an important part of visual arts, fashion, interior design, and many other fields and disciplines. The following is a list of colors. A number of the color swatches below are taken from domain-specific naming schemes such as X11 or HTML4. RGB values are given for each swatch because such standards are defined ...

English style guides prescribe writing the percent sign following the number without any space between (e.g. 50%). [sources 1] However, the International System of Units and ISO 31-0 standard prescribe a space between the number and percent sign, [8] [9] [10] in line with the general practice of using a non-breaking space between a numerical value and its corresponding unit of measurement.
acetyl chloride SOCl 2 acetic acid (i) Li[AlH 4], ether (ii) H 3 O + ethanol Two typical organic reactions of acetic acid Acetic acid undergoes the typical chemical reactions of a carboxylic acid. Upon treatment with a standard base, it converts to metal acetate and water. With strong bases (e.g., organolithium reagents), it can be doubly deprotonated to give LiCH 2 COOLi. Reduction of acetic ...
